| 主权项 | 1. A method of demulsifying an emulsion comprising oil and water, the method comprising: adding a composition to an oil-in-water emulsion, wherein the composition comprises a combination of a cationic alkyl ammonium halide surfactant and an amphoteric betaine surfactant comprising cocoaminopropionic acid, wherein the composition further comprises from about 100 ppm to about 20,000 ppm cationic alkyl ammonium halide surfactant, and wherein the halide of the cationic alkyl ammonium halide surfactant does not comprise chlorine. | ||
